No Ringing when connecting to my phone

[Lyndyloo]

When someone phones me they don't get a ringing tone, but my phone rings normally on my side! How can I stop this happening as people are hanging up because they don't think the call is connecting.

It is happening from a certain number only, or perhaps from people on a certain network?

Usually someone not hearing anything ring is due to a delay in the connection relays (and could be either networks issue). You could log the issue with customer services, and get the person (or people) experiencing the issue to do the same with their network

It's a known issue if you have an esim connected on your account.

I there anything I can do to stop it happening if it is down to having an esim connected to my account?

[Lyndyloo]

It happens on all different networks and when people phone me from a landline!

There is nothing you can physically do, it's a network issue and you need to get O2 to investigate.

O2 are aware but it seems not fixed yet.
